HEATING BATH-TUBS BY STEAM.

SPECIFICATION forming part of Letters Patent No. 255,535, dated March28, 1882,

Application filed November 3,1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES REILLY, a citizen of the United States,residing in Brooklyn,

in the county of Kings and State of New York,

have invented a new and useful Device for the Heating of Bath-Tubs, ofwhich the following is a specification.

My invention consists mainly in the introduction into bath-tubs of anarrangement of steam-heating pipes, by means of which, operating as aradiator before the introduction of the water into the tab, the air ofthe room may be properly warmed, after which, by the introduction of thewater into the bath-tub, the heating-pipes are submerged and thebathingwater raised to any desired temperature.

To enable persons skilled in the art to which my invention pertains tomake, construct, and use the same, I will proceed to describe itsconstruction and operation by reference to the accompanying drawings, inwhich-'- Figure l is a longitudinal sectional elevation Fig. 2, atransverse sectional elevation 3 Fig. 3, a top view of one end of thebathingtub, showing the pipe for the introduction of steam, the sameletters indicatingsimilar parts in the several views.

A is a bath-tub of usual construction; B, a pipe by which thebathing-wateris introduced, and O a pipe by which it is discharged. D isa cylindrical steam-heater, made of metal, the ends of the tube formingthe same being contracted in diameter, so as to unite with a tube orinner cylinder, E, which is set concentrical- 1y with the outercylinder, and through which the water of the bathtub freely circulates,while the steam for heating it is admitted to the annular space betweenthe said tube and the outer cylinder. The steam is admitted into theheater by means of pipe F, and the resulting water of condensation isdischarged by means of pipe G.

The operation of my ihvention is as follows: For the purpose of warmingthe bathing-room the steam is permitted to enter the heater, whichcauses by local rarefaction of the airits rapid circulation throughoutthe apartment. When sutficient warmth has been secured the bathing-wateris admitted into the tub until the heater is submerged, when the wateris circulated in like manner by the expansion and ascent of that portionsurrounding the heater until the whole has acquired the temperaturedesired.

My heuting'apparatus, instead ofbeing placed directly within thebath-tub, may be placed in any suitable chamber or cell connectedtherewith by suitable pipes, (induction and eduction,) through which theupward current of the heated water within the connected chamber or cellwill pass into the bathing-tub by the induction-pipe provided, and bereplaced in the heating chamber or cell by the cooler water of the tubflowing in through the pipe provided for this purpose.

I am aware that the water in bath-tubs has been heated by introducingsteam directly into the water through an open-mouthed pipe provided forthis purpose; but the operation of this device discloses manyobjections, as the introduction into the bath-tub of grease and rustfrom the steam boiler, a certain disagreeable crackling and percussivenoise caused by the sudden condensation of theinjected steam and aconsiderable discharge of steam into the atmosphere of the room, as thewater rises in temperature and is unable to condense the entering steamwith sufficient rapidity to prevent its bubbling up to the surface andbeing there liberated. I therefore do not claim any such device.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination, with 'a bath-tub, of surface steam-heatingpipes placedwithin the tub, arranged andoperating substantially as herein set forth.

JAMES REILLY.
